Effect of Earthquake Frequency Content on Dynamic Response of Concrete Rectangular Tanks Using Coupled Finite Element Method and Smoothed Particle Hydrodynamics

Concrete ground tanks are widely used in storing water, sewage, oil, toxic chemicals and other liquids. Depending on their type of use, they are usually in the category of very important structures of lifelines; Therefore, the dynamic analysis of liquid storage tanks is one of the most important iss...

In this study, the water medium is modeled using smoothed particle hydrodynamics method and tank’s structure modeled by finite element method. The smooth particle hydrodynamics, which is a meshfree method, has many advantages over other traditional grid-based methods.
